What this shows Exal's Innovation Score is 17.5/100 (4th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Exal?

Each dot is one of Exal’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Exal’s own 2.0 claims/patent is at or below the 14.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Exal's grants concentrate

Exal Corporation is a focused PatentsView assignee: 2 CPC subclasses with 15.8% of grants classified under B65D (Containers FOR Storage OR Transport OF Articles OR Materials, e.g. Bags, Barrels, Bottles, Boxes, Cans, Cartons, Crates, Drums, Jars, Tanks, Hoppers, Forwarding CONTAINERS; Accessories, Closures, OR F). Peak complete grant year is 2020 (9 grants) versus a trough of 1 in 2016. By volume, Exal sits between Esperion Therapeutics, Inc. and FCX Solar LLC.

Exal's three-year grant acceleration

Exal Corporation shows 2 grants in 2022–2024 against only 14 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
